The nation of Yugoslavia was formed on December 1, 1918 as a result of the realignment of nations and national boundaries in Europe in the aftermath of World War I. The nation was first named the Kingdom of Serbs, Croats and Slovenes and was renamed the Kingdom of Yugoslavia in 1929. The kingdom occupied the area in the Balkans comprising the present-day states of Bosnia and Herzegovina, Serbia, Montenegro, Republic of Macedonia, and most of present-day Slovenia and Croatia. The United States recognized the newly formed nation and commissioned its first envoy to the kingdom on July 17, 1919. Previously the USA had had an envoy extraordinary and minister plenipotentiary who was commissioned to Romania, Bulgaria, and Serbia while resident in Bucharest, Romania. Towards the end of the 1930s, the diplomatic relations between Belgrade and Washington were raised from ministerial to the ambassadorial level.

At the beginning of World War II, the government of Yugoslavia fled Belgrade and formed a government in exile in London and later in Cairo. During that time the U.S. ambassadors continued to represent the United States in London and Cairo. The embassy was transferred back to Belgrade in 1945.

Between 1943 and 1992 the nation was known by various names, including the Democratic Federative Yugoslavia (1943), the Federal People's Republic of Yugoslavia (1946), and the Socialist Federal Republic of Yugoslavia (1963).

After the breakup of the Socialist Federal Republic of Yugoslavia in 1992, the remnants of the nation, comprising the Republics of Serbia and Montenegro, renamed itself the Federal Republic of Yugoslavia. On May 21, 1992, the United States announced that it did not recognize the Federal Republic. The ambassador had left Belgrade one week earlier. A series of chargés d'affaires represented the U.S. government until 1999, when the embassy was closed.

In 2001 the United States recognized the Federal Republic of Yugoslavia and commissioned an ambassador to Belgrade.

In 2003 the parliament of the Federal Republic of Yugoslavia ratified the Constitutional Charter, establishing a new state union and changing the name of the country from Yugoslavia to Serbia and Montenegro. The U.S. ambassador continued in his post as the ambassador to Serbia and Montenegro.

Political appointee A person who is not a career foreign service officer, but is appointed by the president (often as a reward to political friends).

Appointed The date that the ambassador took the oath of office; also known as “commissioning”. It follows confirmation of a presidential appointment by the Senate, or a Congressional recess appointment by the president. In the case of a recess appointment, the ambassador requires subsequent confirmation by the Senate to remain in office.

Presented credentials The date that the ambassador presented his letter of credence to the head of state or appropriate authority of the receiving nation. At this time the ambassador officially becomes the representative of his country. This would normally occur a short time after the ambassador’s arrival on station. The host nation may reject the ambassador by not receiving the ambassador’s letter, but this occurs only rarely.

Terminated mission Usually the date that the ambassador left the country. In some cases a letter of recall is presented, ending the ambassador’s commission, either as a means of diplomatic protest or because the diplomat is being reassigned elsewhere and replaced by another envoy.

Chargé d'affaires The person in charge of the business of the embassy when there is no ambassador commissioned to the host country. See chargé d'affaires.

Note: The United States announced on May 21, 1992, that it would not recognize the Federal Republic of Yugoslavia, comprising the Republics of Serbia and Montenegro, as the successor to the Socialist Federal Republic of Yugoslavia.

Note: The following officers served as chargés d'affaires ad interim in Belgrade: Robert Rackmales (May 1992–July 1993), Rudolf V. Perina (July 1993–Feb 1996), Lawrence Edward Butler (Feb-Aug 1996), Richard M. Miles (Aug 1996–Mar 1999). The embassy was closed March 23, 1999. Miles and the last Embassy personnel left March 24, and NATO armed forces began military action against Serbia-Montenegro that evening.

Note: The United States again recognized the Federal Republic of Yugoslavia in 2001 and posted an ambassador to that nation.

^MacVeagh was also commissioned to the government-in-exile of Greece; resident in Cairo.

^The government-in-exile of Yugoslavia transferred back to England on March 11, 1944. On July 1, 1944 Rudolf E. Schoenfeld was designated Chargé d'Affaires ad interim near the Government of Yugoslavia established in England.

^Patterson served near the government-in-exile in London. The U.S. Embassy was transferred back to Belgrade March 31, 1945.

^Allen was commissioned during a recess of the Senate and recommissioned after confirmation on February 2, 1950.

^Rankin was commissioned during a recess of the Senat and recommissioned after confirmation on January 29, 1968.

^Leonhart was commissioned to the Socialist Federal Republic of Yugoslavia.

^Montgomery was originally commissioned to the Federal Republic of Yugoslavia and continued to serve after its name was changed to Serbia and Montenegro on February 4, 2003.

President of the United States
–
The President of the United States is the head of state and head of government of the United States. The president directs the executive branch of the government and is the commander-in-chief of the United States Armed Forces. The president is considered to be one of the worlds most powerful political figures, the role includes being the commander-in-chief of the worlds most expensive military with the second largest nuclear arsenal and leading the nation with the largest economy by nominal GDP. The office of President holds significant hard and soft power both in the United States and abroad, Constitution vests the executive power of the United States in the president. The president is empowered to grant federal pardons and reprieves. The president is responsible for dictating the legislative agenda of the party to which the president is a member. The president also directs the foreign and domestic policy of the United States, since the office of President was established in 1789, its power has grown substantially, as has the power of the federal government as a whole. However, nine vice presidents have assumed the presidency without having elected to the office. The Twenty-second Amendment prohibits anyone from being elected president for a third term, in all,44 individuals have served 45 presidencies spanning 57 full four-year terms. On January 20,2017, Donald Trump was sworn in as the 45th, in 1776, the Thirteen Colonies, acting through the Second Continental Congress, declared political independence from Great Britain during the American Revolution. The new states, though independent of each other as nation states, desiring to avoid anything that remotely resembled a monarchy, Congress negotiated the Articles of Confederation to establish a weak alliance between the states. Out from under any monarchy, the states assigned some formerly royal prerogatives to Congress, only after all the states agreed to a resolution settling competing western land claims did the Articles take effect on March 1,1781, when Maryland became the final state to ratify them. In 1783, the Treaty of Paris secured independence for each of the former colonies, with peace at hand, the states each turned toward their own internal affairs. Prospects for the convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washingtons attendance to Philadelphia as a delegate for Virginia. It was through the negotiations at Philadelphia that the presidency framed in the U. S. The first power the Constitution confers upon the president is the veto, the Presentment Clause requires any bill passed by Congress to be presented to the president before it can become law. Once the legislation has been presented, the president has three options, Sign the legislation, the bill becomes law. Veto the legislation and return it to Congress, expressing any objections, in this instance, the president neither signs nor vetoes the legislation

Yugoslavia
–
Yugoslavia was a country in Southeast Europe during most of the 20th century. The Serbian royal House of Karađorđević became the Yugoslav royal dynasty, Yugoslavia gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The country was named after the South Slavic peoples and constituted their first union, following centuries in which the territories had been part of the Ottoman Empire, renamed the Kingdom of Yugoslavia on 3 October 1929, it was invaded by the Axis powers on 6 April 1941. In 1943, a Democratic Federal Yugoslavia was proclaimed by the Partisan resistance, in 1944, the king recognised it as the legitimate government, but in November 1945 the monarchy was abolished. Yugoslavia was renamed the Federal Peoples Republic of Yugoslavia in 1946 and it acquired the territories of Istria, Rijeka, and Zadar from Italy. Partisan leader Josip Broz Tito ruled the country as president until his death in 1980, in 1963, the country was renamed again as the Socialist Federal Republic of Yugoslavia. The constituent six socialist republics that made up the country were the SR Bosnia and Herzegovina, SR Croatia, SR Macedonia, SR Montenegro, SR Serbia, and SR Slovenia. Serbia contained two Socialist Autonomous Provinces, Vojvodina and Kosovo, which after 1974 were largely equal to the members of the federation. After an economic and political crisis in the 1980s and the rise of nationalism, Yugoslavia broke up along its republics borders, at first into five countries, eventually, Serbia and Montenegro accepted the opinion of the Badinter Arbitration Committee about shared succession. Serbia and Montenegro themselves broke up in 2006 and became independent states, the concept of Yugoslavia, as a single state for all South Slavic peoples, emerged in the late 17th century and gained prominence through the Illyrian Movement of the 19th century. The name was created by the combination of the Slavic words jug, Yugoslavia was the result of the Corfu Declaration, as a project of the Serbian Parliament in exile and the Serbian royal Karađorđević dynasty, who became the Yugoslav royal dynasty. The country was formed in 1918 immediately after World War I as the Kingdom of Serbs, Croats and Slovenes by union of the State of Slovenes, Croats and Serbs and it was commonly referred to at the time as the Versailles state. Later, the government renamed the country leading to the first official use of Yugoslavia in 1929, on 6 January 1929 King Alexander I suspended the constitution, banned national political parties, assumed executive power and renamed the country Yugoslavia. He hoped to curb separatist tendencies and mitigate nationalist passions and he imposed a new constitution and relinquished his dictatorship in 1931. None of these three regimes favored the policy pursued by Alexander I, Alexander attempted to create a centralised Yugoslavia. He decided to abolish Yugoslavias historic regions, and new internal boundaries were drawn for provinces or banovinas, the banovinas were named after rivers. Many politicians were jailed or kept under police surveillance, the effect of Alexanders dictatorship was to further alienate the non-Serbs from the idea of unity. During his reign the flags of Yugoslav nations were banned, Alexander was succeeded by his eleven-year-old son Peter II and a regency council headed by his cousin, Prince Paul

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Kingdom of Yugoslavia
–
The Kingdom of Yugoslavia was a state in Southeast Europe and Central Europe, that existed during the interwar period and first half of World War II. It was formed in 1918 by the merger of the provisional State of Slovenes, Croats, the Kingdom of Montenegro had united with Serbia five days previously, while the regions of Kosovo, Vojvodina and Vardar Macedonia were parts of Serbia prior to the unification. For its first eleven years of existence, the Kingdom was officially called the Kingdom of Serbs, Croats and Slovenes, the official name of the state was changed to Kingdom of Yugoslavia by King Alexander I on 3 October 1929. The state was ruled by the Serbian dynasty of Karađorđević, which ruled the Kingdom of Serbia under Peter I from 1903 onwards. Peter I became the first king of Yugoslavia until his death in 1921 and he was succeeded by his son Alexander I, who had been regent for his father. He was known as Alexander the Unifier and he renamed the kingdom Yugoslavia in 1929 and he was assassinated in Marseille by Vlado Chernozemski, a member of the Internal Macedonian Revolutionary Organization, during his visit to France in 1934. The crown passed to his then-still under-aged son Peter and his cousin Paul ruled as Prince regent until 1941, when Peter II would come of age. The royal family flew to London the same year, prior to the country being invaded by the Axis powers, in April 1941, the country was occupied and partitioned by the Axis powers. A royal government-in-exile, recognized by the United Kingdom and, later, in 1944, after pressure from the British Prime Minister Winston Churchill, the King recognized the government of Democratic Federal Yugoslavia as the legitimate government. This was established on 2 November following the signing of the Treaty of Vis by Ivan Šubašić, Trumbić faced initial hostility from Serbian Prime Minister Nikola Pašić, who preferred an enlarged Serbia over a unified Yugoslav state. In 1916, the Serbian Parliament in exile decided on the creation of the Kingdom of Yugoslavia at a meeting inside the Municipal Theatre of Corfu. The Kingdom was formed on 1 December 1918 under the name Kingdom of Serbs, Croats, on 1 December 1918, the new kingdom was proclaimed by Alexander Karađorđević, Prince-Regent for his father, Peter I of Serbia. The creation of the state was supported by pan-Slavists and Serbian nationalists, for the pan-Slavic movement, all of the South Slav people had united into a single state. For Serbian nationalists, the goal of uniting the majority of the Serb population across south-eastern Europe into one state was also achieved. Furthermore, as Serbia already had a government, military, and police force, the newly established Kingdom of Serbs, Croats and Slovenes participated in the Paris Peace Conference with Trumbić as the countrys representative. Almost immediately, it ran into disputes with most of its neighbours, Slovenia was difficult to determine, since it had been an integral part of Austria for 400 years. The Vojvodina region was disputed with Hungary, Macedonia with Bulgaria, a plebiscite was also held in the Province of Carinthia, which opted to remain in Austria. Austrians had formed a majority in this region although numbers reflected that some Slovenes did vote for Carinthia to become part of Austria, the Dalmatian port city of Zadar and a few of the Dalmatian islands were given to Italy

Balkans
–
The Balkan Peninsula, or the Balkans, is a peninsula and a cultural area in Eastern and Southeastern Europe with various and disputed borders. The region takes its name from the Balkan Mountains that stretch from the Serbia-Bulgaria border to the Black Sea, the highest point of the Balkans is Mount Musala 2,925 metres in the Rila mountain range. In Turkish, Balkan means a chain of wooded mountains, the name is still preserved in Central Asia with the Balkan Daglary and the Balkan Province of Turkmenistan. A less popular hypothesis regarding its etymology is that it derived from the Persian Balā-Khāna, from Antiquity through the Middle Ages, the Balkan Mountains had been called by the local Thracian name Haemus. According to Greek mythology, the Thracian king Haemus was turned into a mountain by Zeus as a punishment, a reverse name scheme has also been suggested. D. Dechev considers that Haemus is derived from a Thracian word *saimon, a third possibility is that Haemus derives from the Greek word haema meaning blood. The myth relates to a fight between Zeus and the monster/titan Typhon, Zeus injured Typhon with a thunder bolt and Typhons blood fell on the mountains, from which they got their name. The earliest mention of the name appears in an early 14th-century Arab map, the Ottomans first mention it in a document dated from 1565. There has been no other documented usage of the word to refer to the region before that, there is also a claim about an earlier Bulgar Turkic origin of the word popular in Bulgaria, however it is only an unscholarly assertion. The word was used by the Ottomans in Rumelia in its meaning of mountain, as in Kod̲j̲a-Balkan, Čatal-Balkan, and Ungurus-Balkani̊. The concept of the Balkans was created by the German geographer August Zeune in 1808, during the 1820s, Balkan became the preferred although not yet exclusive term alongside Haemus among British travelers. Among Russian travelers not so burdened by classical toponymy, Balkan was the preferred term, zeunes goal was to have a geographical parallel term to the Italic and Iberian Peninsula, and seemingly nothing more. The gradually acquired political connotations are newer and, to a large extent, after the dissolution of Yugoslavia beginning in June 1991, the term Balkans again received a negative meaning, especially in Croatia and Slovenia, even in casual usage. A European Union initiative of 1999 is called the Stability Pact for South Eastern Europe, and its northern boundary is often given as the Danube, Sava and Kupa Rivers. The Balkan Peninsula has an area of about 470,000 km2. It is more or less identical to the known as Southeastern Europe. As of 1920 until World War II, Italy included Istria, the current territory of Italy includes only the small area around Trieste inside the Balkan Peninsula. However, the regions of Trieste and Istria are not usually considered part of the Balkans by Italian geographers, the Western Balkans is a neologism coined to describe the countries of ex-Yugoslavia and Albania

Bosnia and Herzegovina
–
Bosnia and Herzegovina, sometimes called Bosnia-Herzegovina, and, in short, often known informally as Bosnia, is a country in Southeastern Europe located on the Balkan Peninsula. Sarajevo is the capital and largest city, in the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a larger region and has a moderate continental climate, with hot summers and cold. The southern tip of the country has a Mediterranean climate and plain topography, Bosnia and Herzegovina is a region that traces permanent human settlement back to the Neolithic age, during and after which it was populated by several Illyrian and Celtic civilizations. Culturally, politically, and socially, the country has a rich history, the Ottomans brought Islam to the region, and altered much of the cultural and social outlook of the country. This was followed by annexation into the Austro-Hungarian Monarchy, which lasted up until World War I. In the interwar period, Bosnia was part of the Kingdom of Yugoslavia and after World War II, following the dissolution of Yugoslavia, the country proclaimed independence in 1992, which was followed by the Bosnian War, lasting until late 1995. The country is home to three ethnic groups or, officially, constituent peoples, as specified in the constitution. Bosniaks are the largest group of the three, with Serbs second and Croats third, a native of Bosnia and Herzegovina, regardless of ethnicity, is identified in English as a Bosnian. The terms Herzegovinian and Bosnian are maintained as a rather than ethnic distinction. Moreover, the country was simply called Bosnia until the Austro-Hungarian occupation at the end of the 19th century, Bosnia and Herzegovina has a bicameral legislature and a three-member Presidency composed of a member of each major ethnic group. The Federation of Bosnia and Herzegovina is itself complex and consists of 10 cantons, additionally, the country has been a member of the Council of Europe since April 2002 and a founding member of the Mediterranean Union upon its establishment in July 2008. The name is believed to have derived from the hydronym of the river Bosna coursing through the Bosnian heartland. According to philologist Anton Mayer the name Bosna could be derived from Illyrian Bass-an-as which would be a diversion of the Proto-Indo-European root bos or bogh, meaning the running water. According to English medievalist William Miller the Slavic settlers in Bosnia adapted the Latin designation Basante, to their own idiom by calling the stream Bosna, the name Herzegovina originates from Bosnian magnate Stephen Vukčić Kosačas title, Herceg of Hum and the Coast. Hum, formerly Zahumlje, was a medieval principality that was conquered by the Bosnian Banate in the first half of the 14th century. Bosnia is located in the western Balkans, bordering Croatia to the north and west, Serbia to the east and it has a coastline about 20 kilometres long surrounding the city of Neum. It lies between latitudes 42° and 46° N, and longitudes 15° and 20° E, the countrys name comes from the two regions Bosnia and Herzegovina, which have a very vaguely defined border between them

Montenegro
–
Montenegro is a sovereign state in Southeastern Europe. Its capital and largest city is Podgorica, while Cetinje is designated as the Old Royal Capital. In the 9th century, three Slavic principalities were in the territory of Montenegro, Duklja, roughly corresponding to the half, Travunia, the west, and Rascia. In 1042, archon Stefan Vojislav led a revolt that resulted in the independence of Duklja, Duklja reached its zenith under Vojislavs son, Mihailo, and his grandson Bodin. By the 13th century, Zeta had replaced Duklja when referring to the realm. In the late 14th century, southern Montenegro came under the rule of the Balšić noble family, then the Crnojević noble family, large portions fell under the control of the Ottoman Empire from 1496 to 1878. Parts were controlled by Venice and the First French Empire and Austria-Hungary, from 1515 until 1851, the prince-bishops of Cetinje were the rulers. The House of Petrović-Njegoš ruled the country from 1697 to 1918, from 1918, it was a part of Kingdom of Yugoslavia, which was succeeded by SFR Yugoslavia in 1945, FR Yugoslavia in 1992, and subsequently by the state union of Serbia and Montenegro in 2003. On the basis of a referendum held on 21 May 2006. Montenegro is also a candidate negotiating to join the European Union, on 2 December 2015, Montenegro received an official invitation to join NATO, whereby it would be the 29th member country. This invitation was meant to start accession talks. The countrys name in most Western European languages reflects an adaptation of the Venetian Montenegro, many other languages, particularly nearby ones, use their own direct translation of the term black mountain. Examples are the Albanian name for the country, Mali i Zi, the Greek name Μαυροβούνιο, the Chinese name 黑山, all Slavic languages use slight variations on the Montenegrin name Crna Gora, examples include the Czech Černá Hora and the Polish Czarnogóra. Chechen and Ingush people call the country Ӏаьржаламанчоь, the name Crna Gora came to denote the majority of contemporary Montenegro only in the 15th century. The aforementioned region became known as Old Montenegro by the 19th century to distinguish it from the acquired territory of Brda. Its borders have changed little since then, losing Metohija and gaining the Bay of Kotor, the ISO Alpha-2 code for Montenegro is ME and the Alpha-3 Code is MNE. By 1000 BC, a common Illyrian language and culture had spread across much of the Balkans, interaction amongst groups was not always friendly – hill forts were the most common form of settlement – but distinctive Illyrian art forms such as amber and bronze jewellery evolved. In time, the Illyrians established a federation of tribes centred in what is now Macedonia

Republic of Macedonia
–
Macedonia, officially the Republic of Macedonia, is a country in the Balkan peninsula in Southeast Europe. It is one of the states of the former Yugoslavia. A landlocked country, the Republic of Macedonia has borders with Kosovo to the northwest, Serbia to the north, Bulgaria to the east, Greece to the south, the countrys geography is defined primarily by mountains, valleys, and rivers. The capital and largest city, Skopje, is home to roughly a quarter of the nations 2.06 million inhabitants, the majority of the residents are ethnic Macedonians, a South Slavic people. Albanians form a significant minority at around 25 percent, followed by Turks, Romani, Serbs, Macedonias history dates back to antiquity, beginning with the kingdom of Paeonia, a Thracian polity. In the late sixth century BCE the area was incorporated into the Persian Achaemenid Empire, the Romans conquered the region in the second century BCE and made it part of the much larger province of Macedonia. Macedonia remained part of the Byzantine Empire, and was raided and settled by Slavic peoples beginning in the sixth century CE. Following centuries of contention between the Bulgarian and Byzantine empires, it came under Ottoman dominion from the 14th century. Between the late 19th and early 20th century, a distinct Macedonian identity emerged, although following the Balkan Wars of 1912 and 1913, Macedonia remained a constituent socialist republic within Yugoslavia until its peaceful secession in 1991. Macedonia is a member of the UN and of the Council of Europe, since 2005 it has also been a candidate for joining the European Union and has applied for NATO membership. Although one of the poorest countries in Europe, Macedonia has made significant progress in developing an open, the countrys name derives from the Greek Μακεδονία, a kingdom named after the ancient Macedonians. The name is believed to have meant either highlanders or the tall ones. However, Robert S. P. Beekes supports that both terms are of Pre-Greek substrate origin and cannot be explained in terms of Indo-European morphology, the Republic of Macedonia roughly corresponds to the ancient kingdom of Paeonia, which was located immediately north of the ancient kingdom of Macedonia. In the late 6th century BC, the Achaemenid Persians under Darius the Great conquered the Paeonians, following the loss in the Second Persian invasion of Greece in 479 BC, the Persians eventually withdrew from their European territories, including from what is today the Republic of Macedonia. In 356 BC Philip II of Macedon absorbed the regions of Upper Macedonia, the Romans established the Province of Macedonia in 146 BC. Roman expansion brought the Scupi area under Roman rule in the time of Domitian, and it fell within the Province of Moesia. Whilst Greek remained the dominant language in the part of the Roman empire. Slavic peoples settled in the Balkan region including Macedonia by the late 6th century AD, during the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c.680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, presians reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia
